replacing multiple lines in nvim based on an array

Question

If I have the following content

head = cfg["head"] 
head = cfg["head"] 
head = cfg["head"] 
head = cfg["head"] 

Assuming I have a list as below

:let list = ['head', 'hhea', 'os2', 'post'] 

How can I transform that content into

head = cfg["head"] 
hhea = cfg["hhea"] 
os2 = cfg["os2"] 
post = cfg["post"] 

Answer 1

You could consider using g together with execute

:let list = ['head', 'hhea', 'os2', 'post'] 
:let i = 0 
:'<,'>g/head/exe 's/head/' . list[i] . '/g' | let i += 1

You could also consider the following approach (put, map), although it feels a bit hard‐coded

:pu = map(list, {i, val -> printf('%s = cfg["%s"]', val, val)}) 

---

In this case it works, but the contents of the list will be modified

'<,'>g/head/exe "s/head/" . list->remove(0) . "/g"

Answer 2

Taking your example, if you can first visual select those lines, this :s command may help you:

'<,'>s/head/\=list[line('.')-line("'<")]/g

Note This command doesn't check if the number of lines you selected matches the number of elements in the list
